Antenna design guide for NLM001x Including full example About this document Scope and purpose This antenna design guide is intended to be used for determination of correct parameters for rectangular and square PCB near-field communication (NFC) antenna designs for Infineon’s NLM0011/NLM0010.
Antenna Motion These are some rough notes on the system for moving the antenna in the NSRT. The axes of rotation are EQ (equatorial) and DC (declination). The Arduino Controller The controller uses an Arduino Mega2560 card with an Ethernet Shield. The stepping motor drivers are Geckodrive G213Vs. There are US Digital HD25 incremental encoders ...
Jul 26, 2014 · Antennas wave and propagation 1. Antennas and Propagation Key points 2. 2 Introduction An antenna is a transducer that converts radio frequency electric current to electromagnetic waves that are radiated into space In two-way communication, the same antenna can be used for transmission and reception
Sensor and Simulation Notes Note 491 January 2004 Antenna Beam Steering Concepts for High Power Applications Clifton C. Courtney, Donald E. Voss and Tom McVeety Voss Scientific Albuquerque, NM ABSTRACT There is considerable interest in antennas that are high power capable, conformal to their host platform, and beam peak steerable.

The radio-frequency signal from an antenna is an alternating current. In a radio, the speaker, or headphones, cannot keep up with the rf signal, but after it is detected the speaker can respond. The signal from the antenna in a radio must first be tuned in to separate it from other radio signals.
antenna (located at the origin and orientated along the z-axis) is shown in Fig. 3. Note that this is an 'exploded' view. Fig. 4(a) and (b) show the same eld pattern in the two-dimensional elevation and azimuth planes respectively. Some qualitative observations: The three-dimensional pattern is somewhat torus shaped;
Antennas Andrew Austin 1 Introduction Wire antennas are the oldest and most commonly used of all antenna forms. Designs can be easily fabricated from solid wire or tubular conductors and are (typically) very inexpensive. In this part we will start by considering the short dipole antenna to introduce the concepts, followed by an analysis
Antenna arrays are characterized by their array factor which is given by the formula where N the number of elements making the array , k = 2Pi / wavelength , is the polar angle and is the difference of phase between any two successive elements forming the array .

Compared with conventional antennas, microstrip patch antennas have better prospects and more advantages. They are lighter in weight, smaller in dimensions and they can be easily integrated with RF and microwave systems . However, microstrip antenna have some drawbacks including narrow bandwidth, low power handling capability,
